From b5962a934a4dae3d84590dc8ef290f5fa8fec34b Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Sat, 8 Jun 2019 12:29:02 +0530 Subject: Rampayload: Able to build coreboot without ramstage This patch removes all possible dependencies in order to build platform with CONFIG_RAMPAYLOAD enable(without ramstage). A. Create coreboot separate stage kconfigs This patch creates seperate stage configs as below 1. HAVE_BOOTBLOCK 2. HAVE_VERSTAGE 3. HAVE_ROMSTAGE 4. HAVE_POSTCAR 5. HAVE_RAMSTAGE B. Also ensures below kconfigs are aligned with correct stage configs 1. COMPRESS_RAMSTAGE and RELOCATABLE_RAMSTAGE are now enable if CONFIG_HAVE_RAMSTAGE is selected. 2. COMPRESS_BOOTBLOCK will enable if CONFIG_HAVE_BOOTBLOCK is set 3. COMPRESS_PRERAM_STAGES will enable if CONFIG_HAVE_VERSTAGE || CONFIG_HAVE_ROMSTAGE is selected. C. Also fix compilation issue with !CONFIG_HAVE_RAMSTAGE On x86 platform: Case 1: ramstage do exist: CONFIG_HAVE_RAMSTAGE=1 >> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_x86_32 Case 2: ramstage doesn't exist: CONFIG_HAVE_RAMSTAGE=0 >> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_ This patch fixes Case 2 usecase where platform doesn't select CONFIG_HAVE_RAMSTAGE. Also add option to create sipi_vector.manual based on $(TARGET_STAGE) variable. $(TARGET_STAGE)=ramstage if user selects CONFIG_HAVE_RAMSTAGE $(TARGET_STAGE)=postcar if user selects CONFIG_RAMPAYLOAD Change-Id: I0f7e4174619016c5a54c28bedd52699df417a5b7 Signed-off-by: Subrata Banik Reviewed-on: https://review.coreboot.org/c/coreboot/+/33142 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin --- src/cpu/x86/Makefile.inc | 28 ++++++++++++++++------------ 1 file changed, 16 insertions(+), 12 deletions(-) (limited to 'src/cpu/x86/Makefile.inc') diff --git a/src/cpu/x86/Makefile.inc b/src/cpu/x86/Makefile.inc index 3e8a6648f4..65c092133f 100644 --- a/src/cpu/x86/Makefile.inc +++ b/src/cpu/x86/Makefile.inc @@ -17,23 +17,27 @@ SIPI_RMOD=$(SIPI_ELF).rmod SIPI_BIN=$(SIPI_ELF:.elf=) SIPI_DOTO=$(SIPI_ELF:.elf=.o) +ifeq ($(CONFIG_HAVE_RAMSTAGE),y) +TARGET_STAGE=ramstage +else ifeq ($(CONFIG_RAMPAYLOAD),y) +TARGET_STAGE=postcar +else +$(error Halting the build due to unknown TARGET_STAGE select) +endif + ifeq ($(CONFIG_PARALLEL_MP),y) -ramstage-srcs += $(SIPI_BIN).manual +$(TARGET_STAGE)-srcs += $(SIPI_BIN).manual endif -rmodules_$(ARCH-ramstage-y)-$(CONFIG_PARALLEL_MP) += sipi_vector.S +rmodules_$(ARCH-$(TARGET_STAGE)-y)-$(CONFIG_PARALLEL_MP) += sipi_vector.S -$(SIPI_DOTO): $(call src-to-obj,rmodules_$(ARCH-ramstage-y),src/cpu/x86/sipi_vector.S) - $(CC_rmodules_$(ARCH-ramstage-y)) $(CFLAGS_rmodules_$(ARCH-ramstage-y)) -nostdlib -r -o $@ $^ +$(SIPI_DOTO): $(call src-to-obj,rmodules_$(ARCH-$(TARGET_STAGE)-y),src/cpu/x86/sipi_vector.S) + $(CC_rmodules_$(ARCH-$(TARGET_STAGE)-y)) $(CFLAGS_rmodules_$(ARCH-$(TARGET_STAGE)-y)) -nostdlib -r -o $@ $^ -ifeq ($(CONFIG_ARCH_RAMSTAGE_X86_32),y) -$(eval $(call rmodule_link,$(SIPI_ELF), $(SIPI_DOTO), 0,x86_32)) -else -$(eval $(call rmodule_link,$(SIPI_ELF), $(SIPI_DOTO), 0,x86_64)) -endif +$(eval $(call rmodule_link,$(SIPI_ELF), $(SIPI_DOTO), 0,$(ARCH-$(TARGET_STAGE)-y))) $(SIPI_BIN): $(SIPI_RMOD) - $(OBJCOPY_ramstage) -O binary $< $@ + $(OBJCOPY_$(TARGET_STAGE)) -O binary $< $@ -$(call src-to-obj,ramstage,$(SIPI_BIN).manual): $(SIPI_BIN) +$(call src-to-obj,$(TARGET_STAGE),$(SIPI_BIN).manual): $(SIPI_BIN) @printf " OBJCOPY $(subst $(obj)/,,$(@))\n" - cd $(dir $<); $(OBJCOPY_rmodules_$(ARCH-ramstage-y)) -I binary $(notdir $<) $(target-objcopy) $(abspath $@) + cd $(dir $<); $(OBJCOPY_rmodules_$(ARCH-$(TARGET_STAGE)-y)) -I binary $(notdir $<) $(target-objcopy) $(abspath $@) -- cgit v1.2.3
